A Wilt Disease Op Alfalfa Caused by Fusarium
As stated in the above-mentioned paper (pi), several writers have reported a root rot or wilt of alfalfa with which a species of Fusarium has been associated. Cottam (3) states that the pathogenicity of a root disease of alfalfa in Utah has been traced to the activity of a Fusarium. He describes this disease as being characterized by brown cankerous depressions at the bases of lateral roots, wh...
متن کاملFirst Report on Fusarium Wilt of Zucchini Caused by Fusarium oxysporum, in Korea
Fusarium wilt of zucchini in Jeonju, Korea, was first noticed in May 2013. Symptoms included wilting of the foliage, drying and withering of older leaves, and stunting of plants. Infected plants eventually died during growth. Based on morphological characteristics and phylogenetic analyses of the molecular markers (internal transcribed spacer rDNA and translation elongation factor 1α), the fung...
متن کاملMechanisms of Action and Dose-Response Relationships Governing Biological Control of Fusarium Wilt of Tomato by Nonpathogenic Fusarium spp.
ABSTRACT Three isolates of nonpathogenic Fusarium spp. (CS-1, CS-20, and Fo47), previously shown to reduce the incidence of Fusarium wilt diseases of multiple crops, were evaluated to determine their mechanisms of action and antagonist-pathogen inoculum density relationships. Competition for nutrients, as represented by a reduction in pathogen saprophytic growth in the presence of the biocontro...
متن کاملEffects of Varying Environmental Conditions on Biological Control of Fusarium Wilt of Tomato by Nonpathogenic Fusarium spp.
ABSTRACT The influence of varying environmental and cropping conditions including temperature, light, soil type, pathogen isolate and race, and cultivar of tomato on biological control of Fusarium wilt of tomato by isolates of nonpathogenic Fusarium oxysporum (CS-20 and CS-24) and F. solani (CS-1) was evaluated in greenhouse and growth chamber experiments. Liquid spore suspensions (10(6)/ml) of...
متن کاملControl of Fusarium Oxysporum Causing Fusarium Wilt by Trichoderma Spp and Pseudomonas fluorescens on Arachis hypogaea L
Fusarium wilt diseases caused by the fungus Fusarium oxysporum lead to significant yield losses of crops. Biocontrol agents such asTrichoderma viride , Trichoderma harzianum and Pseudomonas fluorescens are applied to control Fusarium wilt of Arachis hypogaea. Experiments were conducted on the effect of culture filtrates of T.viride (1%), T.harzianum (1.5%), and P. fluorescens (2%) on biochemica...
